Meditation as a Pain Treatment.
Part 2 of an excellent article.

"According to the researchers, 15 healthy volunteers were subjected to painful heat for five minutes from a device attached to their leg while they underwent arterial spin labeling magnetic resonance imaging, a type of brain scan that shows long durations of brain processes.
The scans revealed high activity in the primary somatosensory cortex, a brain region that determines the source and severity of pain.
Then the volunteers attended four 20-minute classes to learn a meditation technique called focused attention, which trained them to focus on breathing and to dismiss other thoughts or emotions.
After the meditation training, the study participants were again subjected to the painful heat on their leg while undergoing the brain scans. The scans revealed a decrease in activity in the primary somatosensory cortex and an increase in the activity in three regions that shape how the body experiences pain: the anterior cingulate cortex, anterior insula and the orbito-frontal cortex.
The ratings that the study participants assigned to the pain decreased 40 percent after they attended the meditation training sessions.
Acute pain and chronic pain
The findings show that meditation affects multiple regions in the brain to relieve pain sensations, said Alex Zautra, a psychology professor at Arizona State University who was not involved with the study.
Changes in breathing rate or heart function didn't account for the differences in pain ratings from before the meditation training to after it, so "changes in attention deployment made possible through training in mindfulness appear to have been the primary mechanism here," Zautra told MyHealthNewsDaily.
People at highest risk for acute pain, including firefighters, police officers and members of the military, stand to benefit the most from these studies, he said.
However, further study is needed before meditation is encouraged as a primary solution for chronic pain, Zautra said.
Some people with chronic pain, like those who have fibromyalgia, may need additional treatment beyond meditation to soothe symptoms, he said.
Zautra authored a study, published last year in the journal Pain, that showed that breathing exercises could decrease pain sensations in healthy women. However, the results were mixed for women with fibromyalgia; only the women who had positive outlooks on life reported decreased pain sensations, his study showed.
